Flanged Butterfly Valve TTV

The TTV flanged butterfly valve is a concentric valve with an elastomeric liner, designed for flow isolation in water networks, process water, wastewater, HVAC, cooling, fire protection, compressed air, and auxiliary industrial lines. The flanged design is chosen when a full mechanical connection to the piping is required instead of a wafer or lug body.

Technical Specifications

Range: DN32–DN2000; flanged tables show dimensions from DN50.
Body: EN-GJL-250.
Flanges: PN10/PN16 and ANSI Class 150.
Connection Standards: ISO 7005, DIN 2501, BS 4504, ANSI B16.5.
Face-to-face / distance between flanges: EN 558 Series 20, ISO 5752 Series 20, referencing API 608 Table 1 and BS 5155 Series 4.
Top Flange: ISO 5211.
Testing: ISO 5208, tightness per API 598.
Coating: Rilsan®.
Operating Pressure: up to 20 bar DN32–DN600, up to 16 bar for DN >600.

Seats and Temperature

Liner selection determines permissible fluid and temperature:

EPDM: -20 to +110 °C, water and neutral fluids.
EPDM HT: up to +130 °C.
NBR / Hypalon: -10 to +90 °C, oils or non-aromatic hydrocarbons after verification.
FKM / Viton: -5 to +180 °C.
Silicone: -40 to +150 °C.

Handling and Automation

Available with hand lever, gearbox, pneumatic actuator double acting, spring return, electric or hydraulic actuator. Actuator selection should be based on DN, ΔP, seat material, and required torque.

Installation and Maintenance

No additional gasket is required when the liner acts as a sealing surface. For end-of-line installation, a downstream counter flange with bolting is required. The manual recommends open/close testing at least once a year, with elastomer wetting before operation.

FAQ

When to choose flanged over wafer?
When full flanged connection, higher mechanical rigidity, or easier alignment in large diameters is required.

Is it a control valve?
No. It can be used for limited throttling, with control over Kv, disc angle, noise, velocity, and liner wear.
